Signor Uzielli has shown that one Tommaso da Vinci, a descendant of Domenico (one of Leonardo's brothers), was a few years ago a peasant at Bottinacio near Montespertoli, and had then in his possession the family papers, which now form part of the archives of the Accademia dei Lincei at Rome. It was proved also that Tommaso had given his eldest son "the glorious name of Leonardo."
